DOOR-LOCK.

A lication-mes July 1,- 1910'. Serial No. 570,005.

To all whom it may concern:

Be it" known that I,- RUSSELL L. .SYVEGER, a citizen of the United States, residing at -Carlisle, in the county of Cumberland and .State of Pennsylvania, have invented a new and useful Door-Lock, of which the followthe said spindle being .n'ally ing is a specification. This lllVGIltlOIlJBlatBS to door locks and one of its objects is to provide simple means whereby the knob spindle of the lock can be secured in or out of engagement with the bolt retracting wing or roll back ofthe lock,

shiftable longitudiintereither of saidpositions.

A further object is to provide means whereby a key can be used for unlocking the spindle -to permit said spindle to be shifted longitudinally into any position desired relative to the said operating wing.

With these and other objects in view the invention consists of certain noveldetails of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the-accompanying drawings the preferred fogm of the invention has been shown.

In said drawings :Figure 1 is a section through the casing of the lock, said sect-ion being taken on the line AB of Fig. 2.

xthe spindle. 5 is a section through aspective view'of a Fig. 2 is a section on line CD Fig. 1. Fig. 3 is a perspective view of a slightly modi- Fi portion of a modified form of lock'and" showing the spindle lock extendin to the bottom of the casing. 1g. 6 is a perform of spindle lock and showing the ad'- joining part of the lock casing, this lock being adapted for use in a reversible lock casing, f

Referring to the figures by characters of reference 1 designatesthe lock casin hav ing a spring pressed latch bolt 2 t erein formed with an elongated opening 3 in which is arranged a-retracting wing or roll back 4- having an angular sleeve 5 projecting therefrom. A knob spindle 6 is slidably and revolubly mounted within the casing 1 and is-provided at intermediate points with an angular collar 7 and a cylindrical collar 8, there being an annular-groove 9 between the two collars and another-annular groove 10 between the-collar 8 and tlie adjoining downwardlyportion of a modified portion of the spindle 6. A slide 11 is mounted within the casing and has a shoul- 'der 12 against which bears a spring 13 which serves-to hold one end of said slide normally. pressed against the spindle at a point between vthe wing or roll back/L and the wall of the casing 1. That end of the slide adapted to contact with the spindle, is preferably formed with an angular recessl' and the other end thereof projects beyond the casing 1 and has a finger piece 15 thereon. A notch 16 is formed in one edge of the slide and is normally locatedadjacent the key-hole 17 formed within the casing 1.

It is to be understood that either of the collars 7 and 8 may be locatedwit-hin the angular sleeve 5. When the collar 7 is arrangedlwithin this sleeve, the spring 13 will automatically seat--the recessed end 14 of slide 11 within the'groove 9. Itwill be seen therefore that when the spindle 6-is rotated, the wing or roll back 4 will be moved therewith and will operate to retract the bolt. 2. hen the collar 8 is arranged within the sleeve 5, the slide '11 will be seated within the groove 10 and will hold the spindle against longitudinal movement. -With the "parts thus arranged, the spindle can be rotated in either direction without causing any movement of the wingor rollback 4.- It will thus be seen that the bolt 2' cannot be retracted unless the spindle 6 l is shifted longitudinally sons to bring the collar 7 into the sleeve 5. This 1S-ObYlOLISlY'iIIlPOSSlblQ unless the slide 11' is shifted out of engage-1 ment with the groove 10. This can only bedone by a person pulling -on the finger piece 15 or by inserting a proper key into the hole 17 and turning it into the notch orrecess 16 so as to force the, strip lon itudinally.

Although in Figs. 1' and '2 t e finger piece of the slide 11-has been shown located above the casing 1., it is to be understood that, if

preferred, the parts may be reversed as shown-iin Fig. 5 and with the. finger p ece ,an opening 19 in theniiddle'portionof a underneath the casing. This is particularly" strip if) extending through the look, for re eeiving the knob spindle, The strip '19 has key receiving recesses 18 therein, so that, when a key is inserted into either of the holes 18 and rotated, it will swing into the adjacent recess 18 and shift the strip 19 longitudinally so as to inove'said strip out of engagement with the spindle. With the key holes 18 arranged as shown in Fig. 6, the casing can be placed with either of the holes uppermost and the lock thus used either at the right or at the left of a door.

Instead of forming notches within. the strips 11 andli) for the reception of the key, an ear or projection 20 may be arranged transversely upon the strip as shown. in Fig. 3, this projection also, if desired, serving as a bearing for the spring 13.

Various changes can of course be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as defined in the appendedclaims.

hat is claimed is 1. A look including a bolt, a roll back, a longitudinally movable spindle having annular grooves, there being a rounded por; tion and an angular portion upon the spindle and adjacent the grooves ei her or" said portions being shiftable intothe roll back,

' and a key-operated spindle holding member normally seated in one of the grooves to hold the spindle against longitudinal movement. i

2. A lock including a casing, a bolt, a roll hack, a longitudimilly mqvable spindle extending through the casing and roll back and having spaced annular grooves there being a cylindrical portion and an angular portion upon the spindle and adjacent the grooves and either of which is shiftable into the roll back, a slide mounted Within the casing and having an opening of variable width through which. the spindle extends, means for nmrmally holding the slide seated within one or the grooves to hold the spindle against longitudinal movement, said slide having key engaging portions, and means for guiding a key to said portions to shitt the slide and release the spindle.

3. A look including a casing, a bolt, a roll back, a longitudinally movable spindle having spaced annular grooves, said spindle being provided with a rounded portion and an. angular portion adjacent thev grooves, either of said portions being movable into theroll back, a slide extending beyond the ca 'b and having an opening through Which the spindle extends, said opening being of variable width and the wall thereof being normally seated Within one of the grooves, and key operated means for shifting the slide out of engagement with the spindle.

In. testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the "oresenee of two Witnesses.
